What Jon Said. Helps to remove the fender liner to get some space to work in there. If you have a brass drift. or long socket extension you want to put it on the remaining bolt heads and give them a sharp rap or two with a hammer. This will help shock them and hopefully make it easier to back them out. (thats what Dave Lenzi advised me).

Be very careful with the remflex as they do not like to be bent at all. Work the new bolts in, in 5 pound increments on your torque wrench. Start with the center two bolts then work out to the outside two. 5 pounds on the wrench at a time. So 5 passes.

Let it heat up then cool down and re check. If you have hi temp anti seize put a little on the bolts.

Not a bad job if your kind of skinny and can lay on top of the tire and reach in there.
